Panel antenna AX-1817P designed for use in set c 4G/2G modems (routers), repeaters and phones GSM1800. Antenna type – common-mode lattice. Recommended for use at the boundaries of the service area, with a weak and unstable level 4G/2G signal, and in the case of a long connecting cable between the modem and the installation point of the antenna. Electrical characteristics Operating frequency range, MHz 1700-1900 Gain, dBi 16÷17 The width of the days in H-plane, degrees 32÷40 Days width in E-plane, degrees 16÷19 The sidelobe level, dB, not more -13 The ratio of forward/reverse, dB not less than 20 Input impedance, Ohm 50 SWR in the frequency range, not more 1,5 Permissible power watts 10 Polarization vertical/horizontal Mechanical characteristics Weight with mount, g 1800 Overall dimensions without mounting, m 0,45х0,24х0,05 Connector N-female Antenna material steel, galvanized steel Protective coating powder polymeric paint Material of protective box Frost polycarbonate with UV-protection ,,,inside...

I can't open this file...!!! But the simulation, is clearly, not correct...

Andrew, please show me, where you found this...???

,,, another variant(MiMo) ...

,,, and a few more pictures with details about the impedance adjustment lines of antenna...

,,, and a variant proposed by the user "com666"...

,,, maybe the * dxf file can help,,, fr4 biquad.dxf pcb biquad.dxf

,,,okay Nikram77,,, if you manage to order PCBs, you can send to me some pieces...??? ,,,,this is *gbr file for pcb FR4... dielectric .gbr

,,,nikram77,, you see, that suits you ... ??? simple biquad.gbr

Test comparison of antennas for the Internet from 'Anteks' & 'Gellan'....

Yes, it seems that I had a mistake in the design, now it works,,, ,,here it"s the modified CST*file....!!!! Pagoda 5.5.cst

,,,, yes, you're right, that's what I ask myself, why ... ??? !!!

Or maybe you want to say something like that.,,(dual frequency=814MHz-2442MHz) ,,,or something like this...

This yagi antenna it pretty simple to execute, but it is worth making an adapting loop still coping lambda / 2,by a double plated pcb circuit

My simulation above is compliant...!!! How long is the coaxial cable ?, this is important ... !!!

,,,for this frequency band, I don't think it's possible...!!! ,,,maybe only a Vivaldi antenna....!!!

I know this, I solved it ... !!! ,,,here it"s the CST*file..... Pagoda 5.5.cst

,,, a first test with wire mesh, with 10mm mesh( without reflector)... ,,,with reflector...

I don't know, but the results of this Pagoda antenna are not eloquent or maybe I'm wrong somewhere,,,,

,,,hi buddy...!!! I do not have the dimensions of this antenna, but I will try to improvise one...!!! I think it is such an antenna...

,,,hi buddy...!!! ,,, you have the antenna pagoda .. ???

oooo, you're right, sorry...!!!! ,,,then ,so to be it...

,,, that could be .... ??? !!!

RC-Concepts,

A Notch Filter is also known as a Band Stop filter or Band Reject Filter. These filters reject/attenuate signals in a specific frequency band called the stop band frequency range and pass the signals above and below this band. For example, if a Notch Filter has a stop band frequency from 1200 MHz to 1300MHz, it will pass all signals from DC to 1200 MHz and above 1300 MHz. It will only block those signals from 1200 MHz to 1300 MHz.
